A timing error removing method includes selecting a logic-level correction location and a first buffer to be inserted at the logic-level correction location, wherein the logic-level correction location and the first buffer are able to remove a timing error in a semiconductor integrated circuit to be designed; and searching for a vacant area in the semiconductor integrated circuit where the first buffer can be placed for the logic-level correction location, and if the vacant area is not found, further searching for a combination of a plurality of buffers smaller than the first buffer, the combination of the plurality of buffers being able to be placed in the semiconductor integrated circuit and being able to replace the first buffer in terms of a delay obtained as if the first buffer is inserted. |
